An object travels along a horizontal straight path at a constant rate. The object travels 1 20 20 1 of the length of the path in 3 4 4 3 second. At that rate, how many seconds does it take the object to travel the entire length of the path?
Answers
Answer:
the number of seconds that needed for the overall path length is 15 seconds
Step-by-step explanation:
The computation of the number of seconds that needed for the overall path length is shown below:
The tiny portion is 1 ÷ 20
And, the entire length is 20 ÷ 20
Now if 1 ÷ 20 is travelled in 3 ÷ 4 path so the time needed is
= 20 × 3 ÷ 4
= 15 seconds
Hence, the number of seconds that needed for the overall path length is 15 seconds

A grocery store purchases cantaloupes from two warehouses, A and B. The
distribution of the diameters from Warehouse A is approximately normal with a
mean of 120 mm and standard deviation of 6 mm.
(a) For a cantaloupe selected at random from Warehouse A, what is the
probability that the cantaloupe will have a diameter greater than 127 mm?
A randomly selected cantaloupe from Warehouse B has the probability of 0.763

40% of their cantaloupes from Warehouse B.

(c) If the randomly selected cantaloupe's diameter is greater than 127 mm, what
is the probability the cantaloupe came from Warehouse B?
A: The probability of cantaloupe having dia. more than 127 is 0.12167.
B: Cantaloupe selected at random from the warehouse, then the probability that has a diameter of more than 127 mm is 0.3782.
C: The probability that the cantaloupe will be from warehouse B given randomly selected cantaloupe's diameter is greater than 127 mm, is 0.8069.
What is probability?The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability is a measure of the likelihood of an event occurring. Also, the favorable number of outcomes cannot be negative.
Given two warehouses, A and B
mean for warehouse A = μ = 120 mm
The standard deviation for warehouse A = σ = 6mm
A: a cantaloupe selected at random from Warehouse A
to find the probability of cantaloupe having a diameter greater than 127 mm = P(x > 127)
P(x > 127) = 1 - P(x ≤ 127)
P(x ≤ 127) = P((x - μ)/σ)
P(x ≤ 127) = P((127 - 120)/6)
P(x ≤ 127) = P(z ≤ 1.66)
P(x ≤ 127) = 0.87833
P(x > 127) = 1 - P(x ≤ 127)
P(x > 127) = 1 - P(x < 127) = 0.12167
probability of cantaloupe having dia. more than 127 is 0.12167.
B: Let event A for distributor A and let event B for distributor B
and event C for a diameter greater than 127 mm.
and given A randomly selected cantaloupe from Warehouse B has a probability of 0.763 that it will have a diameter greater than 127 mm,
and the percentage of cantaloupe provided by B is 40%
rest 60% for A,
therefore, for cantaloupe selected at random, the probability of having a diameter greater than 127 mm is
P(C) = P(C|A)P(A) + P(C|B)P(B)
= 0.12167(0.6) + 0.763(0.4)
= 0.073 + 0.3052
P(C) = 0.3782
cantaloupe selected at random from the warehouse, then the probability that has a diameter of more than 127 mm is 0.3782.
C: the probability the cantaloupe came from Warehouse B, given that the randomly selected cantaloupe's diameter is greater than 127 mm,
P(B|C) = P(B ∩ C)/P(C)
P(B|C) = (P(C|B)P(B))/P(C)
substitute values
P(B|C) = ((0.763)(0.4))/0.3782
P(B|C) = 0.3052/0.3782
P(B|C) = 0.8069
The probability that the cantaloupe will be from warehouse B given randomly selected cantaloupe's diameter is greater than 127 mm, is 0.8069.
Hence the probabilities are,
A; 0.12167
B; 0.3782
C; 0.8069.

A circular garden has a radius of 8 feet. What is the arc length intercepted by a central angle of 150°?
Plz Help
Answers
Answer:
The arc length is 20.95 feet
Step-by-step explanation:
We calculate this using;
length of arc = theta/360 * 2 * pi * r
where theta is the central angle
So we have
length = 150/360 * 2 * 22/7 * 8
length = 20.95 feet
A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth.
Answers
Answer:
1.65 + 0.09s
Step-by-step explanation:
Cost of speaker = 22
Cost per song = $1.25
Sales tax = 7.5%
Sales tax due on entire purchase :
0.075(22 + 1.25s)
1.65 + 0.09375s
To the nearest hundredth :
1.65 + 0.09s
